use models photosynthesis usually produces glucose (c6h12o6) as a final product. what are the sources of the carbon atoms and hydrogen atoms in glucose use a symbolic equation as a model to support your answer

Respuesta :

Answer:

Glucose is made of six carbon atoms, six oxygen atoms, and twelve hydrogen atoms. When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air

The oxygen molecules come from carbon dioxide the hydrogen atoms come from water.

Photosynthesis requires water, carbon dioxide gas, and light. Water is absorbed by the roots and conducted through the xylem to the leaves.

  • Carbon dioxide diffuses from the atmosphere through the stomata across the intercellular spaces to the photosynthetic cells.
  • In the light reactions, chlorophyll traps light.
  • Some of the light is used in the photochemical splitting of water into hydrogen ions and oxygen called photolysis.

2H2O →    4H+   +   O2  

  • In the dark reaction, carbon dioxide reacts with hydrogen ions to form glucose.

CO2 + 4H+   →   (CH2O)2 + H2O  

the general equation:

                      light  

6CO2  +  H2O   →     C6H12O6  +     6O2

Thus, The oxygen molecules come from carbon dioxide the hydrogen atoms come from water.
